Ukukhula ngokukhawuleza kwemfuno yamandla kwihlabathi kuvule indlela yokuphuhliswa kwezinye iindlela zemithombo yendalo. Nangona kunjalo, amalahle asadlala indima ebalulekileyo kumthombo wamandla ophambili kwihlabathi. Amalahle athatha i-29% yobonelelo lwamandla kwihlabathi ngo-2015, kwaye kuqikelelwa ukuba ngo-2035, amalahle aza kuba athatha i-24% yamandla. Njengemveliso engaphantsi kwemveliso yemizi-mveliso yamandla asebenza ngamalahle, ubungakanani bothuthu lwe-coal fly buza kuhlala buphezulu ixesha elide.Uthuthu lwempukane yamalahle iye yaba yinto ephambili ekuxhalabiseni ngendalo ngenxa yokwakheka kwayo okuntsonkothileyo kunye nonyango olungenangqiqo. Kwangaxeshanye, uthuthu lwe-coal fly luyinto enokwenzeka, ekufuneka isetyenziswe ngokukhawuleza ngokufanelekileyo. Okwangoku, ukusetyenziswa kwezixhobo zothuthu lwe-coal fly kubandakanya uluhlu olubanzi lweendawo, kodwa izinga lokusetyenziswa kwexabiso eliphezulu liphantsi. Ingcamango yokusetyenziswa kwexabiso eliphezulu kukufunda iimpawu zothuthu lwe-coal fly. Uthuthu lwe-coal fly lwenziwe ngamasuntswana aqinileyo okanye angenanto angqukuva, amasuntswana e-carbon angatshiyo angaguqukiyo kunye namasuntswana eeminerali afana ne-mullite, i-quartz, i-hematite, njl. Kukho umahluko othile kwiimpawu zomzimba, ukwakheka kweekhemikhali kunye nokwakheka kweeminerali zothuthu lwe-coal fly kwiindawo ezahlukeneyo zokuvelisa. Indlela kunye nenjongo yokusetyenziswa kwayo azifani. Ukwakheka okuntsonkothileyo kothuthu lwe-coal fly ngumqobo omkhulu ekusetyenzisweni kwexabiso eliphezulu. Nangona kunjalo, izinto eziluncedo, ezifana nee-hollow microspheres, i-nonburned carbon, izinto ze-magnetic, njl. zinokuhlulwa kwizinto ezintsonkothileyo ngeendlela ezifanelekileyo zokwahlula. Ukwakheka kweekhemikhali kunye nokwakheka kwezimbiwa zothuthu lwe-fly zizinto eziluhlaza ezixabiso liphantsi kwiimveliso ezinexabiso eliphezulu ezifana nee-geopolymers, iiglasi-ceramics kunye ii-zeolite. Ulwakhiwo lweekhemikhali kunye nobukhulu bokuqala beesuntswana zothuthu lwe-coal fly bunempembelelo enkulu kumandla ee-geopolymers. Iimeko zobugcisa ezifanelekileyo kufuneka zimiselwe ngokusekelwe ekuqwalaseleni ngokupheleleyo iipropati ezisisiseko zothuthu lwe-coal fly xa kulungiselelwa ii-geopolymers. Ngokwendlela yolwakhiwo lweekhemikhali zothuthu lwe-coal fly, iiglasi-ceramics ezilungiselelwe ngothuthu lwe-coal fly ziquka iinkqubo ezimbini: i-CaO-Al2O3-SiO2 kunye ne-MgO-Al2O3-SiO2, kodwa ukusetyenziswa kwamandla kwindlela yokulungiselela kuphezulu. Indlela yokutshiza ngokuthe ngqo enokusetyenziswa kwamandla aphantsi kusafuneka ifundwe ngakumbi kwaye ithandwe. Kukho iimvavanyo ezininzi zokusetyenziswa kwe-zeolite eyenziwe ngothuthu lwe-coal fly, kodwa zimbalwa iimvavanyo zemizi-mveliso ezenziwayo. Uphando lwethiyori malunga nokulungiswa kovavanyo lwe-mesoporous silica kunye ne-silica aerosol alunabunzulu ngokwaneleyo, iimeko zinzima ukuzilawula, kwaye kusekho indlela ende ngaphambi kwemveliso yemizi-mveliso.
